how to make tongue tasteless temporarily(about 5 or 10 minutes)??

After I brush my teeth, about 30 minutes later, I get this guncky thick sticky white stretchy stuff on my cheeks, under my tongue. I use toothpaste with the ADA symbol on it. Just wondering what it is. If I use toothpaste without the ADA logo on it, I don't have this problem.

My dentiist says I will regain feeling in my tongue. Why is my tongue numb, will I get the feeling and taste back.

My dog is getting fits every 2 minutes since last night

On monday i got a canker sore on the bottom left side of my mouth under my tongue next to my gums. Ive been using warm water with salt every day to kill it. Its getting better but now i have little tiny skin with white tips hanging from the bottom of my tongue that are sensitive. Is this because of the Canker sore? or is there something else going on?

I woke up this morning and one of my teeth that I had a root canal done on years ago felt 'exposed' in the back by where my tongue is. The gum has always been a little higher there after the accident but this is more than usual. I got a mirror and looked and it looks like there's a hole in my gum behind that tooth. The gums that are there are above the hole are swollen. It doesn't really hurt unless I push on the swollen gingiva with my tongue. What should I do?
